Heat pump repairs in Godalming: what to expect
A heat pump that is serviced and set up properly keeps running efficiently for many years. Many heat pump faults trace back to settings, low pressure or a worn part rather than the heat pump itself, and those can usually be put right.
For repeated faults in Godalming, the engineer looks at the system design as well as the failed part. We repair heat pumps in Godalming whoever installed them, including older monobloc and split systems.
When a heat pump shows an error, loses pressure or stops heating, an engineer diagnoses the cause and explains the repair and its cost before fixing it.
- Outdoor units that have become noisy, iced up or keep switching on and off
- Rooms or hot water not getting warm enough
- Heat pumps installed by another company that need a second opinion
What's included
- A clear explanation of the fault and a price for the repair before work goes ahead
- Reading of error history and operating data
- Testing of sensors, pumps, valves, pressures and electrics
- System refill, venting and recommissioning after the repair
- Supply and fitting of replacement parts
Outdoor units in exposed spots around Godalming can ice more heavily, so siting is checked as part of any icing fault.
Grants and rules for heat pumps in England
Homes in Godalming can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.

Heat pump repairs in Godalming: questions
How much does a visit cost in Godalming?
The rate for a service or fault-finding visit is agreed before anyone attends. Any repair is priced in writing before parts are ordered, so you decide before work goes ahead.
Can you work on a heat pump in Godalming that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Godalming, whoever fitted them. Tell us the make and model when you get in touch.
Do you also cover Guildford?
Yes. We arrange heat pump servicing and repairs in Guildford, which is about 4 miles north-east of Godalming, and across Surrey.
Can you repair a heat pump installed by another company?
Yes. We carry out fault-finding and repairs on heat pumps installed by other companies, including monobloc and split systems. Tell us the make, model and approximate age when you get in touch, plus any error code shown. If the system is still under the manufacturer's warranty, it may be quicker to contact the original installer or manufacturer first.
Do refrigerant repairs need a specialist?
Yes. Any work on a heat pump's refrigerant circuit, such as tracing a leak, replacing a component or re-gassing, must by law be done by an F-gas certified engineer where the refrigerant is fluorinated, such as R32; units using R290 (propane) need an engineer trained in flammable refrigerants. On split systems the refrigerant runs through pipes inside your home, so leaks there are more likely than on sealed monobloc units.
